India's police said Tuesday that three men were being arrested over a triple-track collision that killed nearly 300 people last month, one of the worst rail accidents in the country's history.
The train crash in eastern Odisha state in June resulted in a packed passenger train being mistakenly diverted onto a loop line and slammed into a stationary goods train loaded with iron ore.
The compartments then struck the carriages of another fast train, the Howrah Superfast Express from Bengaluru, which was passing in the opposite direction.
Three railway employees, all of whom have been charged with culpable homicide and destruction of evidence in a case filed against them on Thursday, a statement from the Central Bureau of Investigation said.
The statement identified the men as two signal engineers and one technician employed with Indian Railways, without giving further details.
The two passenger trains were carrying around 2,000 passengers when the collision happened.
The transports had flipped over, and rescue workers scrambled to pull out people trapped in the wreckage, with scores of bodies laid out under white sheets beside the tracks.
